Wipe that smile off your face

Armed police at Indian airports have been told to cut down on smiling, with officials blaming the 2001 US terror attacks partly on excessive friendliness, local media reported this week.

The Central Industrial Security Force, in charge of aviation safety, will move from a “broad smile system” to a “sufficient smile system”, the Indian Express newspaper said. The move was aimed at making the force “more vigilant than friendly”.
